I know a bumper isn't exactly "hardcore", but since it's fabrication I thought it might fit here. I just finished my next step in my "fab skill building" - first was rocker guards, now the bumper/swingout - next will be some skid plates I think. The best part was that the vast majority of this was made with scrap steel, so it didn't cost much to build.....
Left side view - mine's mounted a little bit further back so I could fit more stuff on there (hi-lift, shovel, axe, jerry can, CB antenna). I gave up a little bit of departure angle, but for now I think it was well worth it to get all this junk organized and solidly mounted instead of just flopping around in my cab. I wanted to balance the load on the swingout front and back to take some stress of the pivot joint. If I find that the loss of departure angle is a problem - I guess I can cut it down and re-do it:D That 31" tire looks pretty small there, but that changed today. I built it big enough to hold 35's with a little room to spare.

Back View - I put the clevis mounts right at the frame width to directly transfer pulling stresses to the frame and welded front and back, as well as the receiver hitch. Mounts are 7/8" thick 2" wide steel.

Right side view - getting the gas can out of the cab was a BIG reason I started this project - man that thing stunk! The jack fits over a stud at the bottom and is held in place by a wing nut on top - one nut and it's off, but seems to be pretty solid. The only rattles come from the handle, and a handle isolator is already on the way.

Frame Brackets - 1/4" x 4" angle iron, cut down and mounted on both sides of the frame.
